Welcome to Seven Forums drpuneet50. That was fun. The issues I ran into is that apparently that drive didn't come with your PC, it's an Asian only model, and the updates seem to end at Vista. That said, this is what I have come up with. At least a starting point. There is a firmware update for this general problem:
This program will upgrade the Firmware for UJ-232AS to Version 1.01 and the following symptoms are improved:
1. Improve the writing performance for Sony BD-R SL 6x Media.
2. Improve the writing performance for some +RW Media.
3. Blu-ray Drive cannot be ejected sometimes.
But finding the exact doenload is the issue for me, since the update isn't listed on the support page for your model. Have a look at these, and see if you currently have Blu-ray Drive UJ-232AS Firmware Upgrade Program Version 1.01.
If not the updtae will hopefully fix your issue, but correct update is tough:
Sony Support D/L
XP Version
Sorry I couldn't locate the particular one for your PC since it wasn't an option when new. Good luck. A Guy
